Geography

Illinois Route 104 passes through the village as its Main Street, leading east and then southeast 21 mi to Jacksonville, the county seat, and west across the river and 50 mi to Quincy.

Marais d'Osier, meaning willow swamp, was the original French name given to the area in the early 1800s.

Closing of Power Ameren power station
In 2011, Ameren Energy Resources Company announced the closure of its power station in Meredosia. The closure resulted in a loss of over 50 jobs, a major economic hit for the small community. The plant closure was related to the cost of meeting environmental regulations. The plant may reopen at some point as a facility to test clean coal technology, according to Ameren.

New bridge
In June 2018 the community celebrated the opening of a new bridge over the Illinois River. The former bridge, constructed in 1936, had become too narrow for modern traffic, and was dismantled during the summer of 2018. The bridge not only links Meredosia to Quincy, Illinois, but serves as an important transportation link between western Illinois and the center of the state.
